Hi. This is probably the only property, so you can't delete it. Here's what you need to do ↓

Thank you so much! Will that keep the component name and all links to it from other files connected?

I wonder why the Figma team doesn’t let us delete the only property by using the -- button. Would be easier and more straight-forward than this work-around. 

But thank you very much for the video!

Connections won't be lost. The component name was a slightly changed, but you can rename it back
